Asheer,

Could you expand on your use case a bit? What are you trying to achieve?

Thanks,

The standard expression language used in Activiti is JUEL (Unified Expression Language - The Java EE 5 Tutorial ).
As far as I know, JUEL supports ternary (conditional) operators.

e.g. ${failed ? 1 : 2}

If process variable failed == true the expressions returns 1, otherwise 2.

Cheers,
Greg
